new and useful lmprovelnentsin lllectlolytio Cells, of which the following is a full. clear,

and exact description.

This invention relates to electrolytic cells and particularly to those cells which employ a U, V. or similar shaped cathode. (ells of snchshapcs may the limited in their hei it'because of the difficulty encountered in racing the dia hragm in )ositiou. which cli cu-lty is great y increase when a cathode is employed which has formed therein a number of crimps or corrugations. To enable the insertion of-a diaphragm in such cells, the cell body was necessarily made wide enough to rovideacccsstoall parts of the interior so 4: lat the-diaplmigm could lucarefully laced in position. The deeper the cell, the wider it hadto he. and this greatly increased the weight of the cell and the floor space occupied by it. without a. corresponding increase in capacity.

An object of my invention is to provide a cell of the U, V, or similar shaped cathode type. in which the material required "for its construction, repair and renewal is reduced to a minimum. I

Another object is to provide a cell of this typoin which the anodes can he placcd in position in a preferred arrangement before the cells are assembled.

nother Object is to provide a cell of this type which is sulliciently light and small 4 to make practicable its suspension from sun ports.

Another object is to provide a cell of this tvpe in which the renewal of the anodes or the chan ing of a diaphragm can be easily and quic 1y accomplished and wlnlc tluccll is suspended.

.-\notherobjcct is to providc u cell of this type which occupies a minimum amount' of horizontal area and which can he built sub stantially to any reasonable height without incrcusing the length or lateral space occuicd. p In carrying'out iny invention 1 may construct my cell of two nuts. or halves. by splitting it longitudinal y alongthe central vertical axis. which parts. whcuthc cell .18 assembled. are detacbably secured together in any suitable manner. Each half has an a cell anode and cathode compartment. While the two halves are ,se arate, the anode, cathode and diaphragm -each half or part can bc carefully and securely placed in pusitiom whereupon the halves or atts cnn he attached together and the ccl is ready for use. 'hen repairs are necessary the two halves orparts are separated. and eitherhalf or part can be repaired without hindrance fr m 'the other half. If a new diaplu-a m is necessary in one half. that can bcsupp ied without disturbing the other hull, thereby efl'ecting a considerable saving: in time and material orcr the prior constructions in which an cntire new diaphragm was necessary if any Change had to he made. If a crimped cathude is used, the diaphragm has to be carefully fitted in said crimps aiiil'sccured there- .in before the anodes are placed in position.

in the old cells having the U. V. or siinilur shaped cathodes, this \vzuspractically impossible unless the cell body was made very widc. but in a cell constructed according-to my invention thc width or thickness can be vcrv small and the height may he comparativcly rcrv grout.

l may also employ an ordinary cell casing and suspend therein a split cathode and diaphragm.togcthcr withthc anode. In this case. thc;parts are first lifted from the casin, and the cathode and diaphragm parts are separated. or replaced. as in the other embodiment above described.

I shall no w desoribc the illustrated embodimcnts of my invcntion' and shall there after point'out my invention in claims.

Fig.1 is a perspwtive of a cell constructed in accordance with my invention:

Fig. 3 is apcrspcctivdof one-half of such Fig. 3 is a transverse vertical-section of a cell;

Fig. 4 is a horizontal section of a cell;

Fin. 5 is a transverse vertical scctiowof a modilicd form of cell. and

Fig. (l is a transvcrsc vertical section. of anothcr modified form of cell.

Rlfll'llllfl' morc mwticularlr to Figs 1 to 4. thc cell body comprises two complcmon tary sections. cnch section having a side wall 1. end walls 2. and a bottom wall '3.

"The bottom walls may carry angle members- 4 adjacent their abutting, edges which members may be secured together many suitahle manner as by bolts 5. The complementary end walls may be secured tomodifications may be of any suitable material such as soapstone or concrete, and the cells of Figs. 5 and ti have the usual outlets for the caustic liquid. and hydrogen and chlorine gas. ()ne of the end walls of each cell may be provided with a suitable gage 3T tol indicate the height of the liquid in the ce 1.

It is obvious that various other modifications may be made in the construction of my apparatus as illustrated in the drawings and above particularly described, within the principle and scope of my invention.
